Subframe Connectors - Mancini vs Mopar vs others

[Mopar Mitch]

Anyone know the differences between the Mancini vs Mopar brand SFC (not just the cost)?  These are the straight kinds that can be welded front/rear.

I'm considering SFC that are the strongest... maybe the straight AutoRustTechnician are the best?

How about the round MagnumForce types? Desirable.. pros/cons?

Your comments are welcome (I can't use, per club racing rules) any type that cuts through the floor, or welds all across the floor; also, the Hotchkis type are not legal since they attach to the leaf spring mount (rules dictate they must only attach to the frame rails).   Ground clearance is alo a factor -- I need as much as possible since the car sits low ... its used for competition autocross and hi-speed road course lapping sessions... and currently driven to/from the events.

(NOTE:  I like Brad's T/A type that he made... perhaps I'll eventually have the same kinds made at a local shop.)

Come on over/up! We can have them done in a Saturday!

I've got the ART ones on my Challenger.  They hang down about 1/4" below the front frame and ~3/4" below the rear frame when installed and have a cut out for the parking brake. 

Here's some pics when I was fitting it

Mitch, if you are still planning on running the car in e/sp then go with the mopar bolt on ones and have them welded on.  Your other choice is the Hotchkis set or do something similar to Brad. Mancini sells the mopar ones.  The AutoRust ones I have on my challenger I needed to slit my floor for so they would not work for your rules set.

Brad -- I'd love to come and visit.. with my Chally!!!.. about a ~12hour drive from NW Chicago?

Shawge -- Thanks for the pics... did you have to cut or notch the floor to make the ART straight ones fit? (Cudazappa said he had to do that with his ART sfcs).  They do look to be thick and robust!

Cudazappa -- Thanks... the Hotchkis SFC for e-bodies are not SCCA E/SP class legal (as with certain other components they sell) due to their design of attaching to the leaf-spring mount... they must only attach to the frame rails (but I like their bent shape... maybe they could be a little thicker/robust for strength.. imo).

Mancini has their own, and they also sell the Mopar units... I'm curious what the actual differences are between them (ok... I could get around and actually call Mancini sooner or later).

They do touch the rear floor boards and I did make two slits per side to get them to fit.  The floor boards could be massaged slightly upwards in those spots with a BFH so that no welding would be required.
